EN45545-2材料及元件防火要求
EN45545-2材料及元件的防火要求EN45545-2最新标准为2013版，其主要关注于材料的燃烧性能、热释放量、烟密度、毒性等性能。
EN45545-2标准根据材料的最终用途，划分为R1-R26共26个不同的类别。
根据车辆类型及操作环境，EN45545-2-2013标准将火灾的危险等级划分为HL1、HL2、HL3，共3个火灾风险等级。
根据车辆运行环境的风险程度，EN45545-2标准将风险划分为EN45545-2 HL1,EN45545-2 HL2,EN45545-2 HL3,这三类风险等级。
其中EN45545-2 HL3要求最高，最为严格。
为了减少车辆运行时的风灾危险程度，要求铁路车辆内装饰材料最好都达到EN45545 HL3类。
EN45545-2 HL1-HL3风险等级根据车辆运行环境及车辆类别来划分等级EN45545-2 HL1: 标准车辆，没有急救培训的员工的自动列车，双甲板车辆在Operation category 1的环境下运行。
EN45545-2 HL2: 卧铺车辆在Operation category 1的环境下运行；标准车辆，没有急救培训的员工的自动列车，双甲板车辆以及卧铺车辆在Operation category 2的环境下运行；标准车辆，没有急救培训的员工的自动列车，双甲板车辆在Operation category 3的环境下运行。
EN45545-2 HL3: 卧铺车辆在Operation category 3的环境下运行；标准车辆，没有急救培训的员工的自动列车，双甲板车辆以及卧铺车辆在Operation category 4的环境下运行。
不同风险等级的EN45545-2测试要求是完全不同的。
EN45545-2 R1危险等级HL1的数据要求：CFE火焰延伸测试≥20；热释放量无要求；Ds(4)烟密度≤600；VOF(4)烟密度≤1200；毒性测试≤1.2。
EN45545-2 R2危险等级HL3的数据要求：CFE火焰延伸测试≥20；热释放量≤90；Ds(4)烟密度≤300；VOF(4)烟密度≤600；毒性测试≤0.9。

窗帘及百叶窗EN45545烟火毒测试
窗帘及百叶窗EN45545-2烟火毒测试, 由南京睿督公司整理窗帘及百叶窗EN45545-2烟火毒测试, 由南京睿督公司整理 窗帘及百叶窗EN45545烟火毒烟火毒测试测试动车、高铁、地铁上的窗帘、百叶窗等纺织品的对其防火阻燃烟雾毒性的要求都比较高，需要根据EN45545-2 R3标准进行测试及评估。
更多具体关于EN45545-2及EN45545-2 R3测试请咨询南京睿督。
EN45545-2标准标准及及EN45545-2 R3测试材料EN45545-2 Railway applications - Fire protection of railway vehicles-Part 2: Requirement for fire behaviour of materials and componentsEN45545-2铁路应用—铁路车辆的防火保护—第2部分:材料和元件的防火要求。
EN45545-2 R3测试材料为在乘客和工作人员区域的窗帘和百叶窗。
火车用窗帘及百叶窗根据EN454545 R3进行测试及评估。
EN45545-2标准概述对于铁路车辆材料的防火测试标准，欧洲各国测试标准及方法均不同，欧盟启动了一个名为Firestarr Project 的计划，旨在研究和建立一套适合于铁路车辆材料的测试，因此欧盟标准EN 45545-2从材料的可燃性、火焰传播速率、热释放量、烟雾释放量和毒性等多个方面进行综合测试及评定。
根据产品的最终用途、火灾时风险程度，EN45545-2标准将测试划分为R1-R26这26个不同的类别。
根据车辆运行的风险程度不同，火灾风险等级分为HL1-HL4(HL1，HL2，HL3，HL4)，HL4火灾风险最高。
窗帘窗帘，，百叶窗等EN45545-2测试项目及标准测试项目及标准如下如下EN ISO 11925-2: 小火焰点燃测试(火焰申请点燃时间为30秒)EN ISO 5660-1: 热释放量测试(根据锥形量热仪法进行热释放量的测试)EN ISO 5659-2: 烟密度测试EN ISO 5659-2: CIT at 8min 毒性测试(根据CIT 毒性指数进行测试)由于火灾风险程度不同，因此各项测试数据都会有不同的要求。

客户必须提供吸塑制品的长、宽、高和所用材料的厚度、颜色和型号（PVC、PET、PS），产品数量和生产周期。
二、业务部门报价：吸塑制品单价的高低跟以下因素有关：吸塑制品的长、宽、高和吸塑成型的复杂程度；所用材料的类型、厚度和颜色；吸塑产品的后道加工工艺（折边、打孔、封边等）、订单数量和订单周期。
报价员会以客户的样品和描述有一个最初报价，最终报价会在打样之后报出。
三、电脑设计：客户对于报价基本认可后，会将要求、实物或是吸塑样品交到业务部，生产调度会要求电脑设计部将客户的实物扫描并结合印刷品的设计，制作出吸塑制品的平面设计图四、吸塑打样：客户认可电脑设计稿后，生产调度会根据吸塑产品的复杂程度决定采用哪种方式开发模具（石膏模、铜模、铝模），开发周期3-5天。

All Rights Reserved.Lesson Objectives•Learn about:–Tray Efficiencies–Sizing (Design) of Trays and Packing–Rating of Trays and PackingRadFrac Efficiencies•Efficiency type–Overall efficiency–Vaporization efficiencies–Murphree efficiencies•Can be specified–Overall–By stage–For column sections–For individual components© 2002 AspenTech. All Rights Reserved.Overall Efficiency•Direct conversion of actual trays to theoretical plates.•Not directly input to model; instead Overall Efficiency sets the number of stages in the RadFrac block.•Example:–Column with condenser,reboiler and 30 trays–At 70% efficiency, 30 trays = 21 theoretical stages–Add stages for condenser and reboiler=> 23 total•Most common, but least flexible method.© 2002 AspenTech. All Rights Reserved.© 2002 AspenTech. All Rights Reserved.Vaporization Efficiency•At equilibrium:•With efficiency:•Efficiency should be different for different components.•As ηdecreases, the vapor pressure must increase which means that the temperature must increase.•Using vaporization efficiency alters the T profile and this may alter relative volatility.•In general it is better to use Murphree efficiencies.ii i i i i i x K y x K y η==© 2002 AspenTech. All Rights Reserved.Murphree Efficiency1,,,1,,,+−+−=j i y j i x j i K j i y j i y M j i Eff •Strictly, this is a Murphree vapor efficiency.•Subscripts are i for components and j for stages.•Many correlations exist for Murphree efficienciesSpecifying Efficiencies in the Column•RadFrac Efficiencies Options sheet•Do not specify efficiencies in both the column and in the tray rating forms© 2002 AspenTech. All Rights Reserved.The Problem with Efficiency•Efficiencies vary enormously –they can be under 10% or over 100%.•Efficiencies vary with composition, with purity, and withlocation in the column.•Efficiencies are different for different components.»Next to physical properties, this is the most importantthing to know to successfully model a column.© 2002 AspenTech. All Rights Reserved.© 2002 AspenTech. All Rights Reserved.Determining Column Efficiency•Previous experience.–Be sure experience is comparable•Generalized correlations.•Fit to plant data.–Use Data-fit to regress Murphree efficiency to data•RateFrac can be used to calculate efficiencies.–RateFrac calculates actual separation–Efficiency backed out from calculated compositions•Vendor packages.© 2002 AspenTech. All Rights Reserved.HETP•Comments similar to those for tray efficiency–It is important–It is hard to know well•RateFrac can be used to calculate HETP.–RateFrac calculates actual separation for specified height ofpacking–Separation is converted to NTU, and NTU to HTU•Use of vendor data is common.© 2002 AspenTech. All Rights Reserved.Sizing and Rating for Trays and Packing (1)•Aspen Plus has extensive capabilities to size, rate, andperform pressure drop calculations for trayed andpacked columns.•The calculations are based on vendor-recommendedprocedures when available. When vendor proceduresare not available, well-established literature methods areused.•You can use the computed pressure drop to update thecolumn pressure profile.© 2002 AspenTech. All Rights Reserved.Sizing and Rating for Trays and Packing (2)•Rating Mode–Specify column section diameter and other tray or packingdetails.–Model calculates performance and hydraulic information suchas flooding approach,downcomer backup, and pressure drop.•Sizing Mode–Model determines column diameter to satisfy the floodingapproach or pressure drop* specified for each stage. Thelargest diameter is selected.*pressure drop specification valid for packed columns only© 2002 AspenTech. All Rights Reserved.Sizing and Rating for Trays and Packing (3)•For sizing and rating calculations, column is divided intosections–Each section can have a different tray type, packing type, anddiameter.–The tray details can vary from section to section.–A column can have an unlimited number of sections.–You can size and rate the same section with different types oftrays and packing.© 2002 AspenTech. All Rights Reserved.Sizing and Rating for Trays and Packing (4)•Aspen Plus calculates sizing and performanceparameters such as:–Column diameter–Flooding approach or approach to maximum capacity–Downcomer backup–Pressure drop•These results are based on:–Column loadings (vapor and liquid traffic)–Tray geometry or Packing characteristics–Transport properties© 2002 AspenTech. All Rights Reserved.Sizing and Rating for Trays and Packing (5)•Use the following Tray/Packing forms to enter specifications:–Tray Sizing–Tray Rating–Pack Sizing–Pack Rating •These capabilities are available in the following column unit operation models:–RadFrac–MultiFrac–PetroFrac© 2002 AspenTech.

All Rights Reserved.Trays (2)•The values for the number of caps and number of valves applies for each panel. For example, two-pass trayshave two A panels for tray AA, and two B panels for tray BB. Therefore, the number of caps per panel is thenumber of caps per tray divided by two.
